It is by the method that described sleeve pipe is vertically arranged on the sole plate：It is recessed that one is opened up on the sole plate
Groove, the depth of groove are less than the thickness of the sole plate, described sleeve pipe are inserted in the groove and fixed.
The method that the through hole is applied in described sleeve pipe is：The controlled valve is opened, brill is utilized in described sleeve pipe
Lever apparatus drills the sole plate until forming through hole in the soil body of lower section；Afterwards by set described in the boring rod set lift-off
Pipe, and close the controlled valve.
The controlled valve is located in described sleeve pipe above the position of the sole plate upper surface.
A kind of application for being related to pattern on any above-mentioned underground engineering sole plate, it is characterised in that apply the cloth
Hole mode carries out sluicing decompression, comprises the following steps：After applying the completion through hole and closing the controlled valve, described
Sleeve upper end muzzle, which connects one, has the chimney filter of filter core；The chimney filter is connected with outlet pipe, opens the switch valve in described sleeve pipe
Door, underground water enters described sleeve pipe and the chimney filter through the through hole, and is arranged after chimney filter filtering from the outlet pipe
Go out.
A kind of application for being related to pattern on any above-mentioned underground engineering sole plate, it is characterised in that apply the cloth
Hole mode carries out grouting and reinforcing, comprises the following steps：After applying the completion through hole and closing the controlled valve, by described in
The same slip casting machine connection of upper port of sleeve pipe, opens the controlled valve and slip casting machine, the priming petock silt particle into described sleeve pipe
Slurry, the cement mortar enters below the sole plate through the through hole carries out grouting and reinforcing in the soil body, after slip casting to be done
Close the controlled valve.
It is an advantage of the invention that pattern is simple, by carrying out pore-forming in the sleeve pipe with controlled valve, to prevent
Generation underground water is prominent after sole plate is drilled gushes, in addition, the pattern can be applied to carry out the sluicing below sole plate
Decompression operation and grouting and reinforcing construction.
